Tree Population in the U.S.

This amazing map shows tree population and density in the United States. Created by Josef Kellndorfer and Wayne Walker of Woods Hole Research Center, the map was generated based on a series of data sources including readings collected from space-based radars, satellite sensors, computer models, and simply counting trees the old-fashioned way. The objective was to help NASA determine how the world’s forests have the potential to store more carbon in the future.

In comparison, the map below shows just how little forested area there is in the United States relative to Canada.
